They are generally thought to be called wisdom teeth because they appear so late â much later than the other teeth, at an age where people are presumably wiser than as a child, when the other teeth erupt. The term probably came as a translation of the Latin dens sapientiae.
Over time the jawbone became smaller and all 32 teeth could no longer fit properly. As wisdom teeth erupt they can crowd the other teeth and cause problems. Some even become impacted and do not fully erupt because there is no room and they are blocked by other teeth. Not everyone has wisdom teeth, however. At least, they may never erupt beyond the surface. There are a number of reasons for this, according to researchers. These include the angle and root development of the tooth, it's size, and the space that's available in the jawbone.
